"binder in which the front and back covers-and p:

the-back of the binderare made of asingle piece of sheet material with anovel type of hinge which eliminates looseness and play along the linesof juncture of the front and back covers and the back of the ,binderwithout interfering withthe free movement of the frontandback covers forthe purpose of open ng and closingthe binder.

'back covers atsubstantial right angles to the back of the binder and Fig. 6 is asectionon the i fEiaB- The .back board 5 of thebinder is madepLa lengthdefining the overall dimensions .ofjthefim ;ished binder. It may be madeof any flexible type .of board, such as cardboard composite board or thelike, normally substantially stiff but capable of flexing. Two parallelrows of small holes or perforations 2--3 are formed through the backboard by punching, drilling or like operations.

These rows of holes 2-3 border or outl'ne the back 4 of the binder andin a binder which is substantially inches long and 9 inches wide, thedistance apart of the two rows of holes 23 is substantially 1% inches.The size of the holes 2--3 are preferably made of the order of thethickness of an ordinary dressmakers pin and in a book of the sizementioned it is preferred to form about 15 holes to the inch, the linesof holes extending from the top to the bottom edges of the back board l.The back of the book consequently exhibits two spaced rows of holes,adjoining holes being separated by narrow necks 6 of the material ofwhich the back board is made. The rows of holes 2-3 provide twoweakening lines crosswise 0f the binder and the necks provide connectingsections between holes, which necks or connecting sections tend toretain the front and back covers and the back of the binder in the formof a single unit, but nevertheless capable of permitting the coverportions to hinge along the line of the holes 2-3 and the necks 6. InFig. 4. a section, of a series of such holes, is illustrated togetherwith the connecting necks 6 considerably enlarged for the purpose ofillustration. Two

The inside face'hof *the ba'ck i of I the binder is covered withasuitable covering Ill,-such-as woven; fabric. whichrnaybe" impregnatedwith a rubber or-other' like oornpound. Paper or other I suitablematerial, may also be -usedas the covering material. 'Such covering Illextends-from the top to the bottom edges of the inside face 9 coveringalso the holes 2-3 and necks 6 and also overlaps the portions of thereinforcing plates I and 8 which lie near the holes 23. The degree ofoverlap of such plates is optional but it should be Of the order of ofan inch. Such covering is adhered entirely over the inside face 9 andover the rows of holes 23, the necks 6, and along the inside end edgesof the plates 7 and 8 closely following the contour thereof in orderthat play in the relation of the covering I0 and the parts underlying itis eliminated. The outside face of the entire back board I is alsocovered with a suitable covering II, preferably with a single sheet ofpaper. The covering I I is adhered over the entire surface of the backboard I of the binder. the holes 2-3 and the necks 6 and is lapped overall of the outside edges of said back and a short distance over all ofthe inside face thereof, as is shown at I2 in Fig. 6. It is to be notedthat such overlap of the inside face of the back board overlies thecovering I 0 and conforms to the contours of the inside face of thebinder. Finishing sheets of paper I3--I4 are adhered on the inside facesof the reinforcing plates I and 8 overlying the outside edges of thecovering II! and the edges E2 of the covering II.

The coverings H! and II are applied, without looseness, while the backboard I and the reinforcing plates 1 and 8 are fiat. The book when openlies fiat and when closed assumed a bowed or rounded back, as shown inFig. 5. The bowed or rounded configuration of the back is assumedautomatically when the book is closed for the first time and continuesas a permanent characteristic. The automatic bowing or rounding of thebook back is regarded as a valuable feature of this invention inasmuchas no separate manufacturing operation is required to produce it. Thefinished book when closed has a cushioned or springy feel when pressedwith the hands or fingers.

The holes 2-3 may be drilled, punched or otherwise formed but it is notnecessary to clean the waste from the holes or to have the holes exactlycylindrical. The important factor is that the holes be formed substantally in line and that they be so closely associated that the necksbetween holes will readily bend, but nevertheless continue to serve asconnections between the front and back covers and the back of thebinder. When the binder is finished and the two covers are bent towardeach other to book formation, two hinges are automatically formeddirectly along the line of holes 2 and 3 and the necks B.

I claim:

1. A binder comprising a backboard of substantially uniform thicknessthroughout and defining the shape and contour of the binder when 'inflat condition, two lines of spaced perforations in the backboardbordering and defining the back of the binder, adjoining perforations ofeach line of perforations being closely related, of the order of 16perforations to the running inch, connecting necks between adjoiningperforations, said necks uniting the back of the binder and the left andright members thereof, said perforations and necks constituting hingesupon which said left and right members are relatively movable, areinforcing plate carried by each of said left and right members, theinner edges of the reinforcing plates being spaced from said lines ofperforations but when the binder is in fiat condition, not more than thethickness of said plates so that the edges of the plates, adjacent theperforations, overlie the perforations as the cover is bent from open toclosed position and a covering adhered directly to the inside surface ofthe binder back and said perforation lines and extending over the innerend edges of said reinforcing plates and over and being adhered to theinner top faces of said reinforcing plates for a distance inside of saidedges and a facing overlying the outer portions of the backboard.

- 2. A binder according to claim 1 in which the perforations are of asize of the order of the thickness of an ordinary dressmakers pin.

3. A binder comprising a backboard, two spaced lines of perforations insaid board, said lines of perforations running crosswise of the binderand substantially from the top to the bottom edges thereof, connectingnecks between perforations, the lines of perforations defining the outeredges of the back of the binder and the lines along which the covermembers of the binder bend, said necks connecting the back of the binderand the left and right cover members, a reinforcing plate carried byeach of said left and right cover members, the inner edges of thereinforcing plates being spaced from said lines of perforations, but,when the binder is in flat condition, not more than the thickness ofsaid plates so that the edges of the plates, adjacent the perforations,overlie the perforations as the cover is bent from open to closedposition, and a coverin overlying said perforations, the inside surfaceof the back of the binder and said necks and adhered to said surfaces ofthe back and necks, a covering, comprising a single sheet of material,overlying the outer faces of the cover members, said perforations, saidnecks and back of the binder and adhered to the outer surfaces of saidcover members, necks and back of the binder.
